PACKAGE LIFTELR Application led August 14, 1922. Serial 581,602.

To all wher/1,7125 may concern:

Be it known that I, PAUL LARsEN, a citizen of the United States of yAmerica, anda resident of Kenosha, county of Kenosha;y and State of Wisconsin, have invented certain new and useful Improvements in Package Lifters, of which the following is a specification.v

My invention relates to package lifters, and has for its object the construction of a device adapted to lift packages and remove them from high shelves where they are noteasily reached except by the use of a ladder.

In the accompanying drawings- Fig. 1 is a side elevation with a package shown in dotted lines;

Fig. 2 is a plan;v

Fig. 3 is a sectional elevation corresponding to Fig. 1, but with the. hook adjnstet to engage the edge of a receptacle;

Fig. 4L is a front elevation of Fig. 2;

Fig. 5 is a detail of the hook; and

Fig. 6 is a section on line 6 6 of Fig. 1.

On the handle 10 is secured a channel or guide 1l, and sliding in said guide is a T-shaped bar 12. rI`he guide is secured in place by a. screw 13 (Fig. 3), and by a brace 14 which extends from the end of the channel and is secured to the side of the handle 10 by a screw 15. The guide 11 has wings 1G which bear against the .side of the T-bar 12 and produce friction thereon. The object is to make the T-bar so that it may be moved by hand to any position in the guide 11 and will stay at the position to which it is adjusted.

The front end ,of the T-bar 12 carries a T-shaped arm 17 which rises at right angles to the bar 12, and has a head 18 thereon. The part 17 is in fact an extension of the part 12, the parts 12 and 17 being of the shape of a carpenters square, except that the legs of the square are T-shapedinstead of flat. The parte 17 and 12 may be considered as being an adjustable carrier.

Un the top of the head 1S is a guide 19 in which is a slightly curved strip 2O made of spring steel. The strip 2O has therein a. series of holes 21, any one of which is adapted to lit on a pin 22 in the center of the guide 19. At the forward end of the guide 19 the lips which guide the strip 2O are bent down over the upper face of said strip, but at the rear end of said guide these lips are not bent down but remain as vertical flanges 23 at each edge of the strip 20.

forward of the pin 22 so as to release it from said pin and move it to adjustment withsome other hole 21 engaging pin 22. In other words, the guide 19 as a whole serves to hold the strip 2O in a fixed position with some particular hole 21 engaging` pin 22, but at the same time it permits a manual adjustment of the strip Ato some other position by bending it just forward of the pin 22 and sliding it in the guide 119.

Mounted upon the T 17 is a slide 21 ony which is a block 25 having surfaces` 2G on the front face thereof. These surfaces 2G are removed from each other a short distance and are Preferably of some soft material such as rubber, .which has a large frictional coefficient. Pivoted at 27 on slide 2li is a bell. crank lever 28 provided with a pin 29 adapted to enter oneor another of a series of holes in the T 17. A spring 81k` acts to normally maintain engagement of pin 29 with a hole 30. lBy manually pressing uponlever 28 so as to compress spring 31, the pin 29 is freed, land the slide 2&1 may be moved to any other adjustment on T 17.

The forward end of the strip 20 isr bent downward to form a hook 32 having sharp corners 33 adapted to engage the object to be lifted. From the hook 32 backward for a short distance the forward end of strip 20 is stifened by striking up the central part to form a ribor bead 34.

Let it be supposed that the object to be removed from a high shelf is the box B of Fig 1. The strip 20 is adjusted in guide 19 to the proper position for this size of box. This may be by trial, or the different holes 21 may be marked to indicate specific boxes, and the adjustment may be by such mark. If the box is near the edge of the shelf, then the adjustment of the T 12 in guide 11 may be that shown in Fig. 1, or any adjustment near that. If the required box is back a considerable distance on the shelf, then the T 12 is adjusted to the right in guide 11.

The block 25 will normally be at about the position shown, but may be raised 'for short packages or lowered for long ones.

Having the proper adjustments, the handle l() is inclined forward until the T 17 is about vertical, and the hook 32 is pushed back over the top of the boX until the said hook drops behind the box. The handle is then moved to vertical position, and the box is caught between the hook 32 and the frictionA 'faces on block 25. In this position the weight of the box itself, bearing against' the ulcrum 26, furnishes the force which grips the box. Ilhe handle l0 may then be raised to lift the box clear of the shell, and then lowered to bring the box to any desired position. The box is readily removed by hand, or will drop of itself it the handle is inclined so as to bring the T 17 to vertical or nearly vertical position.

Fig. 3 shows the adjustment of the strip 2O when the hook 32 is made to grip the inside of a receptacle R, or any body which had a flange projecting upward.

YW hen a round object, as a can, is engaged, the convex side of the can comes adjacent to the space between the surfaces 26 (Fig. el). This gives a three-point bearing for the can.

What I claim is:

l. Ina device of the class described, a ulcrum arranged to engage the side of a i package a short distance below its upper edge, a hook arranged to engage the opposite side of the package at a point above that engaged by the iulcrum, and a handle by which the package is tilted to an inclined position so that the weight of said paclnige serves to grip it between the ulcrum and the hook.

2. In a package lifter, a resilient strip of metal having a series of holes therein and a hook on its end, a guide within which the strip is supported, and adjustable, and a pin supported by the guide and entering a hole in the strip, said strip being releasable from the pin by Ibending said strip.

3. In a package lifter, a resilient strip of metal having a hook on its end,- a guide within Ywhich the strip is supported and movable, and interlocking connections between strip and guide for normally holding the strip in iXed position in the guide, said interlocking connections being releasable by bending the strip.

4:. In a package lifter, a handle, an arm supported thereon, a ulcrum secured to thearm, a hook carried by said arm, and independent adjustable devices or the hook and tulcrum, said hook and fulcrum being arranged to engage opposite sides of a package to be lifted.

5. In ay package lifter, a ulcruin arranged to engage one side of a package, a hook arranged toengage the'opposite side of the package, a handle upon which said parts are supported, means for adjusting the fulcruin in one direction, and means for adjusting the hook in a. direction perpendicular to the fulcrum direction.

6. In a package lifter, a handle, an adjustable carrier thereon, and a hook and a fulcrum mounted upon the carrier, said hook and fulcrum being arranged to engage opposite sides of an object to be lifted.

7. In a package lifter, a handle, a guide thereon, a carrier supported in said guide and adjustable to diiferent positions thereon, and package engaging devices supported on said carrier, said parts being so constructed that the engaging devices Will support or release a package by a'movement of the-V handle and without a movement of the engaging devices with respect to each other.

8. In a package litter,v a handle, a guide thereon, a carrier supported in said guide and adjustable to diierent positions therein, a fulcrum supported by and adjustable on said carrier, and a hook supported by and adjustable on said carrier in a direction perpendicular tothe direction of adjustment of said fulcrum.
